.NEAR TERM...
(Rest of today and tonight)
Issued at 219 PM CDT Fri May 15 2026

Fire weather is ramping up across our west with RH values dropping
to near 10 percent along our western border and southerly winds in
the 20 to 30 mph range, gusting to near 40 mph (strongest winds
along an axis from western north Texas / southwest Oklahoma up
through central Oklahoma). The most extreme fire weather conditions
will be centered in southwest Oklahoma and adjacent north Texas
where the stronger winds overlap with the dry air and volatile
fuels. Dry lightning will also be a risk factor in this area this
evening.

Temperatures will rise into the 100 to 105 degree range across
western Oklahoma, with upper 80s / lower 90s expected through
central Oklahoma. Several sites will approach record values. Parts
of southwest Oklahoma may approach heat advisory criteria, but this
should be localized and effects will be mitigated by partly cloudy
skies, low humidities, and breezy winds.

Isolated to widely scattered elevated storms are expected to
initiate off the dryline again late this afternoon with downburst
winds as the main hazard. CAMs suggest western north Texas as the
most likely area for these storms with a secondary signal in far
northwest Oklahoma. As of this writing, we`re starting to see some
notable cumulus develop in the southeast Texas panhandle. Similar to
last night, there is also a risk for heat bursts and wake lows with
lingering showers through the night.

.SHORT TERM...
(Saturday through Sunday night)
Issued at 219 PM CDT Fri May 15 2026

Another hot day on Saturday with fire weather expected in the west.

The dryline is expected to set up a bit farther west, giving us RH
values in the mid to upper teens across western and northwestern
Oklahoma. This will combine with gusty winds to yield near critical
fire weather conditions.

Isolated dryline convection will be possible Saturday afternoon and
evening, though probabilities will be lower due to capping. The
strongest signals for storms are again western north Texas with a
secondary signal in far northwest Oklahoma. Large hail and damaging
winds would be the primary hazards with any storms that develop.

Sunday`s fire weather risk will be focused in northwest Oklahoma
where gusty south winds (20 to 30 mph, gusting to 40 mph) and low RH
values (teens) will combine over volatile fuels (90-95th percentile)
producing critical fire danger conditions.

Dryline convection will again be possible Sunday afternoon and
evening with two subtle differences. Upper level forcing will be
stronger, giving a modest increase in storm chances (still looking
at isolated to widely scattered storms). And low level moisture will
be increased, allowing for a low risk for tornadoes in addition to
hail and damaging winds.

.LONG TERM...
(Monday through Thursday)
Issued at 300 AM CDT Fri May 15 2026

For Monday, the primary shortwave trough is forecast to lift into
the Plains with synopic-scale ascent overspreading the region in
tandem with a strong low-level jet. A highly unstable air mass is
expected by Monday afternoon to the east of the dryline with deep,
low-level moisture. While the current forecast track of the
shortwave trough keeps the strongest flow/shear to our north,
vertical wind shear will be more than sufficient for supercells
with the potential for damaging wind gusts, large hail, and
tornadoes. With the primary wave passing by on Monday,
thunderstorm coverage is expected to be the greatest on this day.

By Monday night into Tuesday morning, a cold front will move
through, which should allow a line of thunderstorms to advance
from northwest to southeast. As a result, there will be a
continued threat of severe weather through the overnight hours.

Beyond Tuesday, an unsettled weather pattern is forecast to
persist across the Southern Plains with the potential for
additional shortwave troughs to move across the region with a
daily chance for thunderstorms through the end of the week.

.AVIATION...
(06Z TAFS)
Issued at 1134 PM CDT Fri May 15 2026

Isolated showers (and perhaps a thunderstorm) will continue across
the area into Saturday morning, although the potential is too low
to include a PROB30 group at most of the TAF sites. But gusty
winds will be possible under and near any of these showers and
storms. Saturday looks to be a repeat with gusty southerly winds,
isolated showers and storms redeveloping during the day, and the
potential of gusty winds near any of the showers or storms
tomorrow.
